The Radxa ROCK Pi E is a compact and cost-effective single board computer aimed squarely at networking and IoT applications, rather than general desktop use. It is built around the Rockchip RK3328, a quad-core Arm Cortex-A53 processor running at 1.3GHz, and pairs it with DDR4 memory available in 512MB, 1GB or 2GB configurations depending on the variant purchased.
Its standout feature is dual Ethernet: a 1000M port that supports Power over Ethernet with an add-on PoE HAT, alongside a second 100M port. That combination suits use as a small router, a network bridge or a PoE-powered sensor gateway where running a single cable for both power and data is a real convenience.
Storage options include eMMC modules from 4GB up to 32GB, and a microSD card slot for the simplest setup. Wireless comes in WiFi 4 with Bluetooth 4.2, or WiFi 5 with Bluetooth 5, depending on the module fitted, and an external antenna connector is supported. A single USB 3.0 Type-A host port covers external drives or peripherals, and a 4-ring 3.5mm headphone jack is present for audio output.
Recommended operating temperature is 0 to 50C, and the board itself measures 56mm x 65mm (2.5 x 2.2 inches), which is small enough to fit into a compact networking enclosure alongside a switch or modem.
Builders working on home routers, network-attached sensors, PoE-powered IoT gateways or other compact Linux networking projects will find the ROCK Pi E's Ethernet and PoE features the main draw. If you need a general-purpose desktop-style SBC instead, a board with HDMI output and more RAM would be a better fit.
